         <p> We present a demo for performing object segmentation with training a Yolov8-seg on wheel Image dataset. The model was trained on 696 training images and validated on 199 images.</p>
         <p><strong>Usage:</strong></p>
-        <p>You can upload wheel Image images, and the demo will provide you with your segmented image.</p>
+        <p>You can upload Tennis-Court images, and the demo will provide you with your segmented image.</p>
         <p><strong>Dataset:</strong></p>
         <p>The dataset contains 3,146 images and is formatted in COCO style. To facilitate usage with YOLOv8-seg, we have converted it into YOLOv8 format.</p>
